Metallic nano-cavity light emitters with a cavity volume of 0.19 λ<sub>0</sub><sup>3</sup> and the active region is completely encapsulated by metal is demonstrated with current injection at room temperature.
SUMMARY We present the theory and experiment of metal-cavity nanolasers and nanoLEDs flip-chip bonded to silicon under electrical injection at room temperature. We first review the recent progress on micro-and nanolasers. We then present the design rule and our theoretical model. We show the experimental results of our metal-cavity surface-emitting… (More)
We have demonstrated both slow light in the absorption regime and fast light in the gain regime of a 1.55 microm quantum-dot semiconductor optical amplifier at room temperature. The theory with coherent population oscillations and four-wave mixing effects agrees well with the experimental results. We have observed a larger phase delay at the excited state… (More)
We designed, fabricated, and characterized thermal performances of Fabry-Pérot quantum-dot lasers with both metal-coated and conventional dielectric waveguides. With proper design, metals, such as Ag, Au, Cu, and Al can function as a low loss waveguide wall as well as an efficient heat remover. Metal-cavity waveguide lasers showed excellent threshold and… (More)
